That's one opinion. The fact that most apps I've checked so far actually guard
against "broken environment" speaks for itself.

1) Sometimes you will run out of memory and just die, regardless of what kind of precautionary code you write.
2) In library code that can be invoked many times, yes, it's important to provide diagnostics.
3) In code that only executes once and then exits, it's pointless.

This is just common sense, life is short, put the effort where it matters.
